Jumper Table Summary
Selecting the CPU Frequency
With the help of Pentium II VID signal and SMbus, this motherboard is jumper-
less design.
The CPU frequency selection is set by going into:
BOIS Setup  Chipset Features Setup  CPU Clock Frequency
(The possible setting is 66.8, 68.5, 75, 83.3, 100, 103, 112, 117, 124, 129, 133.3,
138, 143, 148 and 153 MHz)
BOIS Setup  Chipset Features Setup  CPU Clock Ratio
(The possible setting is 1.5x, 2x, 2.5x, 3x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x,
7.5x, and 8x)
INTEL Pentium II CPU Core Frequency Ratio External Bus Clock
Pentium II - 233 233MHz = 3.5x 66MHz
Pentium II - 266 266MHz = 4x 66MHz
Pentium II - 300 300MHz = 4.5x 66MHz
Pentium II - 333 333MHz = 5x 66MHz
Pentium II - 350 350MHz= 3.5x 100MHz
Pentium II - 400 400MHz= 4x 100MHz
Pentium II - 450 450MHz= 4.5x 100MHz
Warning: INTEL 440BX chipset supports maximum
100MHz external CPU bus clock, the higher clock
settings are for internal test only. These settings exceed
the specification of BX chipset, which may cause
serious system damage.
